VAS Generator

A tool to create Visual Analogue Scales (VAS) for online studies

This tool is to design VAS that can be used in online studies (e.g., Funke & Reips, 2012; Reips & Funke, 2008). Just follow the 4 steps below to create a VAS for your own online survey. This service is free of charge. If you have any questions or comments, please use the contact form. As this tool is still under development, there may be some minor issues with usability. We are working on it.1 Set the parameters stated below and click "generate/modify VAS". Default values are pre-selected.

Length:

pixel

Left Anchor:

Right Anchor:

2 Mark the scale and click "read out VAS value" to see the value that will be transmitted. The number of possible values is equal to the number of pixels. Modify the VAS according to your needs and apply changes by clicking "generate/modify VAS".

Click "generate/modify VAS" for a preview.
